    1) 1, 3, 28, 38, 41, 77, 78, 79 SA/NSA

    2) 41, 78 SA/NSA/Sub6

    3) 1, 41, 78, 79 SA/NSA

    4) 1, 3, 41, 77, 78 SA/NSA

    Why different phones different range of frequency?
    The Telco 5G use which frequency?

    Because they auction off frequency ranges to different cellphone carriers. (Everyone can't use the same frequencies.)
    5G sub-6GHz uses the standard (LTE) bands. These include 600-960MHz and 1700-2400MHz. They often also use the ISM bands, specifically the 2.4GHz band (although these cannot be 'reserved' for the phone.) These also include the 802.11 (wifi) and Bluetooth frequencies.

    5G NR also uses millimeter wave bands. These are currently 24-28 and 39-40GHz.

    Of course. Many phones have limited bands they can transmit and receive on. Often they are optimized for a single carrier, who uses specific ranges of frequencies. Also most carriers do not support millimeter wave.
